The current situation is as follows: Pilot markets three different converters and two different cartridges. Two of the converters reported in 2011, CON-20 and CON-50, are discontinued.

The three converters on production are named CON-40, CON-70, and CON-W. The number refer to their price in Japan: JPY 400 for the CON-40, and JPY 700 for the CON-70. The CON-W only works on the pens that implemented the "double-spare" cartridge in the 1960s. Nominally, it is only served as a spare part and some retailers demand the “broken” pen to be sent for fixing. However, Maruzen and Itoya at their main shops in Tokyo (at least) sell the CON-W without any problem. Its price is JPY 700.

The new guy in town, the CON-40. It holds about 0.5 ml of ink and costs JPY 400.

All the cartridges and converters covered on this Chronicle. From left to right, CON-70 in steel and in black, CON-50 new and old, CON-40, CON-20, two "single spare" cartridges, two Petit cartridges, CON-W. With the obvious exception of the CON-W, all of them share the same mouth dimensions and, provided they could fit inside the barrel, could be used in any "single spare" cartridge/converter Pilot pen.

As for cartridges, the two types are the regular one, formerly named as “single-spare”, and the cartridge specific for the Pilot Petit pens (::1::, ::2::, ::3::). Single spare cartridges do not fit inside the Petit pen, and the only problem of the Petit cartridges to fit in regular Pilot pens are two small plastic notches at the opening of the cartridges. They can easily be removed with a blade.

Petit cartridge on top. Single spare cartridge on bottom. Note the small notches on the former. They prevent the use of the small cartridges on many Pilot pens that, otherwise, could use them. Removing them is easy with a blade.

The following table summarizes the present situation and includes the data of the recently discontinued converters CON-20 and CON-50.
